the easy way to bend it would be nail 2 peices of 2x4 together along 1 side, get a peice of shiny metal from home depot, check in the ductwork section, you can use cold air return .
just cut it to the right size, measure in both sides the same and draw a line.then slide the metal into your 2x4 break, stand on break and lift metal.
then repeat on the other side.
i used to do custom sheet metal on the sides of apartment buildings and that how we made everything
